Some scholars conducted a community health survey on 1 466 men aged 30 to 79 years in the Boston area of the United States from 2002 to 2005 and found that male patients who consumed more lycopene, β-carotene, total carotenoids or vitamin A, The incidence of lower urinary tract symptoms (LUTS) is reduced by 40% to 50%, and the results of lycopene intake are the most obvious. Another clinical trial better clarified the causal relationship between lycopene and lowering prostate specific antigen (PSA) levels and inhibiting benign prostatic hyperplasia.
Therefore, lycopene can improve the lower urinary tract symptoms in patients with benign prostatic hyperplasia and prostate cancer, and can also reduce the prostate-specific antigen (PSA) level in patients with benign prostatic hyperplasia and prostate cancer, and delay the progression of the disease. However, the preventive effect of benign prostatic hyperplasia and prostate cancer is still controversial. The U.S. Food and Drug Administration (FDA) believes that "there is currently no research confirming that lycopene can prevent and reduce the risk of prostate cancer."
